HanaHaki—a disease in which the victim coughs up flower petals due to unrequited love. You just so happened to have it.

Kite is your best friend, and has been for many years now. Though, since about a year ago, you’ve had a crush on him. But… You fear that he wont reciprocate your feelings. He always refers to you as a friend…

Lately, you haven’t went out much. So Kite invited you to his place to hang out. Even if you don’t feel like it… You do it for him. Will you be able to hide your disease from him?
